Worked on the numpy/numpy repository to deliver Windows 11 ARM64 wheel support, expanding the package’s installability across architectures. Addressed the technical challenges of cross-platform build configuration by adjusting Meson-based build scripts and refining Python packaging workflows. Improved ARM64 test reliability through targeted test messaging updates and environment handling, ensuring clearer CI outputs and more robust test coverage for ARM64 systems. Focused on build automation and CI/CD processes using Python and YAML, with additional attention to test cleanliness and maintenance. The work enabled broader distribution of numpy wheels and enhanced the clarity and reliability of ARM64 continuous integration environments.
